To all whom it may concern..-

Be it known that I, WILLIAM B. ARNOLD, of North Abington, in the county Plymouth and State of Massachusetts, have invented an Improvement in Hinges, of which the following description, in connection with the accompanying drawings, isa specification, like letters on the drawings representing like parts. My invention is an improved hinge, being a division of my application, Serial-No. 596,367, filed June 22, 1896, and has for its object the provision of a hinge which, while inexpensive in manufacture, shall at the same time possess superior qualities of strength and especially resistance to longitudinal strains.

To this end my invention comprises a hinge made in two parts, constituting, respectively, the leaves thereof, each being doubled over on itself and interlocked about the hingepintle, the opposite portions of each leaf be ing pinched together adjacent the pintle and thence extended outwardly and the leaves provided remote from the pintle with enlargements for the retention thereof in the wood or material in which it may be embedded.

The details of construction and further advantages of my invention will be more particularly set forth in the following description, and the invention will be defined in the accom panying claim, reference being had to the drawings forming a part of this specification and illustrative of a preferred embodiment of my invention. 7

In the drawings, Figure l is a plan View of one of the hinge-blanks. Fig. 2 is a similar view showing the leaves of the hinge ready to be joined to form the completed hinge. Fig. 3 is a side elevation thereof. Fig. 4 is a perspective view of the completed hinge. Fig.5 is a vertical longitudinal section showing my improved hinge in operative positon securing two adjacent members.

In the formation of my hinge I take two blanks a, one of which is shown in Fig. 1, and bend each blank back upon itself at its middle, so thatthe' folded-over middle portion of the blank will constitute a cylindrical portion a as is indicated in Fig. 3, to receive the hinge-pintle a.

The opposite cylindrical portions a of the leaves A A are respectively cut away, so as the outer free ends of the leaves, Where the latter are shown oppositely and outwardly curved or rolled at a to cooperate and form locking enlargements, preferably in cylindrical form, to be driven or embedded edgewise transversely to the length of the hinge in the material connected by the hinge, thereby preventing the hinge from drawing out of the said material. I

The operation of my improved hinge will be clearly understood by reference to Fig. 5, where the hinge is shown as securing two adjacent portions, each made up of two boards or plates 17 12, secured together by screws 19 each board or plate being grooved on its inner face to receive the enlargements a of the hinge and recessed to receive the leaves A A. The hinge is secured in place either by being put in proper position on the two boards I) b and then having the top boards I) I) laid thereon and fastened to the under boards by the screws 19 or in case the boards I) b have been already secured together, or in case each leaf of the hinge were to be securedin one solid piece, the boards or solid piece It will be evident from the above description that the enlargements a not only hold the parts together, offering strong resistance to longitudinal strains, but also serve to hold the hinge in place without requiring any usual screws to be passed through the leaves of the hinge.

Themetal or material of which the hinge is made will preferably be of such character as to cause the portions a to spring some- What away from each other, as shown in Figs. 3 and 4-, so that the cylindrical. free ends may be pinched together tightly before being driven into the Wood, and will then tend to spring apart and hold more firmly in their places.

This hinge is exceedingly strong, resisting strains in every direction, the several parts thereof sustaining each other and giving a bracing and trussing effect and resistance, which is of great practical value.

' Having fully described my invention, What I claim, and desire to secure by Letters Patent, is-

As an article of manufacture, a hinge having two leaves intermediately bent back on themselves, and overlapped around a central hinge-pintle, the opposite portions of each ol. said leaves being pinched together adjacent the pintle and said leaves having lateral enlargeinents formed in said pinched-together port-ions, removed from the pintle, and projecting outwardly from the leaves, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

YVILLIAM B. ARNOLD.
